FERDINAND HOETZL, OF PHILADELPHIA, PENNSYLVANIA.

JOURNAL-BOX FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 608,332, dated August 2, 1898. Application filed February 9, 1898, Seria1No. 669,622. (Ndmodeh) To all whom it may concern:

Be it known that I, FERDINAND HOETZL, a subject of the Emperor of Austria-Hungary, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in J ournal- Boxes for Railway- Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in journal-boxes for railway and other cars, and

has for its objects, first, improvements in means for maintaining a continuous flow of oil over the axle during the whole time thecar is in motion, and, second, improvements for securingand holding together the upper and lower sections of a journal-box.

The invention consists, essentially, first, in a chamber located in the journal-box above the brass, divided into two sections by a low partition, whereby the forward compartment of said chamberprovides a means for separating dirt; grit, &c.,,from the oil in its passage therethrough, and, second, in improvements in bolts and means for lockingthe same upon the j ournal-boxes for the purposeof securing the two sections thereof together.

Theinvention further consists in the novel construction'and arrangement of the several I parts of thedevice, as hereinafter described,

illustratedin the drawings, and moreparticu; larly, pointed out in the claims hereunto appended. I j Y In the accompanying drawings,Figure l'is a longitudinal vertical section through a j our nal-box embodying my invention. Fig. 2 is a front elevation. of the journal-box. Fig. 3 is a transverse vertical section as on line row of Fig. 1. Fig. 4 is a plan View of said jourvention as applied to a journal-box such as is used on ordinary railway-cars.

The numeral 1 designates the journal-box; 2, the car-axle; 3, the wheel thereon, and 4 the journal on the end of the axle.

The form of box that I prefer to use is made in two sections or halves, 5 being the upper section and 6 the lower section. These two parts of the box aresecurely held together by means of novel locking-bolts 7, hereinafter referredto. A rubber strip 8, placed between the two sections, insures atight connection.

The journal 4 extends some distance into the main oil reservoir 9, and has secured thereon two outwardly-extending arms 10 10. On the ends of each of these arms is formed two spoon-like depressions 11 11, which during the rotation of the journal dip into and scoop up the oil lying in the front end of the reservoir 9, dischargingsaid oil. into the of the troughs 12. After the oil has been discharged into the troughs 12 it will flow out through the openings .13 13 into an adjacent chamber 14, and from thence by way of the duct 15 in the bearingblock 16 to the journal 4, dripping from the said jou'rnal into the oil-reservoir 9, and, passing to the front thereof, is again dipped up by the spoons 11 11, From the foregoin g it will be seen that by the rotation of the'axle there is maintained a continuous flowof oil over the journal.

Extending across the chamber 14 and located some distance inside of the openings 18 is a low partition 17, that divides said chamber14 into two compartments, the outer part serving to catch any grit, sand, &c., which willsettle at the bottom before the oil passes over the said partition.

7 I To prevent the bearing from becoming overheated and resulting in what istermed a hot box, caused through neglect to supply the main reservoir with a sufficient quantity of oil, I providean auxiliary oil-reservoir 18,

said auxiliary reservoir being located above the chamber 14 and provided with a depending pipe 19, on the lower end of which and resting upon the floor of the chamber it is ing the locking-pieces so as to bring the proa head 2t formed of copper or other good heat-conducting metal. Attached to thehead 20 is an upwardly-extending copper stem 20, that projects some distance into the pipe 19. Surrounding the upwardly-extending stem 20 is a cylindrical packing or collar 21, of wax or other fusible material, which effectually closes the pipe and prevents any oil escaping from the auxiliary oil-reservoir 18.

Should the bearing-block 16 become everheated from want of oil, the heat will be conducted through the iloor of the chamber 11 to the head 20 and stem 20 and melt the cylindrical. wax packing or collar 21., allowing the oil in the auxiliary reservoir 18 to pass down the pipe 19 and through the cut-away portion 22 into the chamber 11-, passing from thence through the duct 15 onto the journal 1 and filling the main oil-reservoir, from which it will be dipped or scooped up by the revolving spoons 11 11 and be again passed over the journal in the regular way.

Fitted in the guideways 3O 30 on the front wall 31 of the journal-box is a slide .1 designed to close the opening through which the oil is introduced to the main reservoir 9. This slide is provided with a latch 32, pivoted to said slide at 33. Formed in the wall 31 is a notch 31-, which registers with the lower end of the latch 32. The upper end 35 of the latch 32, extending outwardly under a hood or projection 36 on the slide, keeps the lower end in the notch by gravity. The said hood or projection 36 serves the double purpose of protecting the latch from injury and also affording a means for manipulating the slide. By applying pressure underneath the outwardlyprojecting end 35 of the latch it will be disengaged from the notch 31, and the slide can be raised.

On the sections 5 and 6 of the journal-box are arranged lugs 37 and 38, respectively, through which pass the before mentioned locking-bolts 7, provided on their lower ends with segmental heads 39, (see Figs. 8 and 9,) which are adapted to fit into corresponding depressions 10, formed in the under side of the lugs The upper ends of the bolts 7 are screw-threaded to receive the nuts 11, which are screwed down hard upon the bottom of the depression 1 2 in the lugs 37. Locking-pieces t3, provided with openings corresponding in shape to the nuts t1, are then slipped over said nuts, after which the nuts are given a slight turn backward, when the projecting ends et-t of the locking-pieces 4.3 will enter offsets in thelug 37, abutting against the steps 15, as shown in Figs. 8 and 0, which limit their movement. Interposed between the heads 39 and the surface of the depression 10 are spring or other suitable yielding washers 16, preferably of soft rubber, which are compressed when the nuts 4-1 are screwed tightlyto place. The reaction of these springwashers take up any slack occasioned by the slight backward turn of the nut 11 when turnjeeting ends it into the offsets in the lugs 37. This construction insures a tight and solid connection between the upper and lower sce tions of the journal-box and overcomes any liability of the nuts .tl working loose.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a journal-box the combination of the oil-reservoi r 9, having therein the trough or troughs 12, the oil-chamber1l-, a partition 17 dividing said ehamberinto two compartments, the said chamber communicating with the trough 12, and the d not 15, passing through the bearing-block 16, with the journal 4, having on the end thereof the arm or arms 10, provided with the spoon-like depressions 11, said spoon-like depressions being adapted to dip into the oil and throw it into the troughs as the axle revolves, substantially as shown and for the purpose described.

2. In a journal-box the combination of the oil-reservoir 9, having therein the trough or troughs 12, the oil-chamber 11-, having therein the low partition 17, dividing said chamber into two compartments, the forward one of which forming a settling-chamber for the oils passing therethrough and communicating with the duct 15, passing through the bearing-block 16, with the journal i extending into the oil-reservoir and having thereon the arm or arms 10, provided with the oppositelydisposed spoon-like depressions adapted to convey the oil from the oil-reservoir to the troughs 12, as the said journal revolves, substantially as shown and for the purpose described.

3. In a journal-box, the combination of the upper section 5, having thereon the lugs 37, and the lower sect-i011 (3, having thereon the lugs 38, with the segmental headed bolts 7, fitting into the lug 3S, and provided withthe spring-washer 113, the nut 11, fitting on the end of the bolt 7, and the locking-pieces -13, fitting around the nut 11, the free ends of said locking-picces adapted to pass under offsets formed in the lugs 37, all arranged substantially as shown and for the purpose described.

t. A device for secu ring together the upper and lower sections of a 'journal-box having thereon extending lugs provided with openings that register, consisting of a screw-threaded bolt, a nut fitting on the screw-threaded end and a locking-piece fitting around said nut, the free end of said locking-piece adapted to project under an undercut recess in the lug on the top section, and the lower end of said bolt having thereon an irregulanshapcd head that fits into a corresponding depression on the under side of the lug in the lower section and a spring-washer interposed between the head of the boltand the under side of the lug, substantially as shown and described.

5. In a journal-box the combination of the upper section 5 having thereon lugs L and IIO 6. In a two-part journal-box the sections thereof provided with projecting lugs adapted to receive and hold locking-bolts; in combination with bolts, yielding Washers therefor, nut-s thereon,suitable locking-pieces, and means for locking and holding said lockingpieces securely in the lugs of one of said sections, as set forth.

7. In a journal-box for railway or other cars, a suitable slide fitting in ways 30 on said 20 journal-box, and a pivoted latch 32in the upper part of said slide adapted to have its in ner end automatically engage the wall of the journal-box to hold said slide in locked position.

8. A journal-box for railway or other cars, provided with means adapted to close an opening in said journal-box, consisting of a slide set in ways 30 on said journal-box, there being an opening in said slide near the top thereof, and a pivoted latch 35 adapted to automatically engage a wall of said journal box to hold the said slide in locked position, and a hood 36 at the top of said slide, adapted to protect the handle of the latch 35, and also to afford a means whereby the slide may be raised, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
